Three smaller porcelain Edison Battery jar lids. All clean, in great shape, large bold embossing. Two embossed EDISON Made in USA,, the third, looking a bit older, embossed EDISON PRIMARY BATTERY, three patent dates 1908 to 1911, and Thomas A Edison signature embossed around the bottom. The RR employee who gave me these said finding them in good shape is tough. Some wear around the center hole on the older one, not bad, actually adds to it's aged look. See closer picture next. How about $30 for all three, plus shipping. Medium flat rate box. Thanks
